2. Consider the modulated signal $z(t) = A(t)\cos(\omega_c t + \theta_c)$, where $\omega_c$ is known but $\theta_c$ is unknown. We would like to recover $A(t)$ from $z(t)$. a. Show that $z(t) = x(t)\cos(\omega_c t) + y(t)$ and express $x(t)$ and $y(t)$ in terms of $A(t)$ and $\theta_c$. [10 Marks] b. Discuss how $x(t)$ can be recovered from $z(t)$ using amplitude modulation followed by filtering. [15 Marks] c. Discuss how $y(t)$ can be recovered from $z(t)$ using amplitude modulation followed by filtering. [10 Marks] d. Express $A(t)$ in term of $x(t)$ and $y(t)$ with no reference to $\theta_c$ and show in block diagram how to recover $A(t)$ from $z(t)$. [15 Marks]
